  1. The Scientific Method Standard 1

  2. Forming a Question • What is the basis for your experiment. What do you want to know? • Examples: • How does Alka Seltzer relieve an upset stomach? • Are left-handed people more creative than right-handed people? • Is Bounty Paper towels really the quicker picker upper?

  3. Background Information • You have a question…but now you have to do some research…this research is your background material. • The background material is the basis for structuring your experiment… Example: • Background material: Alka Seltzer • The stomach has a pH of 2, which is acidic. When a stomach begins to feel sour, it means the pH is lower or more acidic. The pH needs to be neutralized with a base—Alka Seltzer has calcium which may be a base that could raise the pH of the stomach acid.

  4. Hypothesis Statement • The hypothesis statement has three parts: • Part I • Identifies what you will be testing in your experiment. • “If I add Alka Seltzer to an acidic solution” • Part II • Makes a prediction about what you believe will be the outcome of your experiment • “Then I predict it will raise the pH of the solution” • Part II • Connects the prediction to the background material. • “because Alka Seltzer has a calcium—which is a base”

  5. Hypothesis Statement Template If I ___________________ Part I __________then I predict that ___________Part II ___________ will occur because _________Part III___________.
